I remember we had a problem with some version of libxft used in Familiar or OZ
some time ago. Does Xtscal work for you?
It might be worth checking if there is a more up to date library in
org.openembedded.dev.

I'm not absolutely sure what happened here, but that looks like you ran out of
memory. Try to check where in this application this problem occurs - that might
give some indication if you ran out of resources of if it is a bug.
